The MK25 configuration is defined by its USN-style anchor engraving on the left side of the slide ahead of the ejection port, along with a DoD-style UID/data-matrix label marked with MFR and PNO MK-25. This example also has a factory case label identifying MK-25 dated 20-FEB-2026.
Construction is purpose-built for durability: a stainless-steel slide with a Nitron finish over an aluminum-alloy frame with a hard-coat anodized finish. Internal components receive a phosphate treatment for added corrosion resistance.
Controls and sighting are set up for duty use. It runs a DA/SA action with a decocking lever and exposed hammer, and it wears fixed 3-dot tritium night sights. The frame includes a true MIL-STD-1913 three-slot Picatinny rail for mounting compatible lights or accessories.
Chambered in 9mm Luger, the full-size P226 MK25 carries a 15+1 capacity. It comes with three 15-round steel magazines and textured black polymer grip panels with SIG SAUER/P226 logos for a secure hold.
